Worm End Play
50. Select shim pack to give no end play but still permit
turning with not more than 3A pound pressure exerted at rim of
steering wheel when the nuts are drawn down tight on the cover.
51. Dip sector and shaft in gear lubricant, insert in housing
cover and assemble cover with eccentric sleeve (F), lock sleeve
and jam nut (E), also cover nuts (A) with lockwashers.
52. Put steering wheel and pitman arm in place and tighten
nuts.
Cross Shaft Adjustment
53. See that housing cover nuts (A) and jam nut (E), Figure
(1601), are tightened securely.
54. Turn hand wheel to either extreme and back an eighth of
turn. Gripping ball arm at hub (B), Figure (1601), shaft should
rotate freely without a particle of end play. To adjust loosen lock
nut (D) and turn screw (C).
Adjusting Worm and Sector Mesh
55. Back off nuts (A), Figure (1601), one-quarter turn and
eccentric jam nut (E) one-half turn.
56. Turn steering wheel to its mid-position of travel with
trade-marked spoke (trade-mark impressed into under face of
spoke opposite keyway) to point straight downward. This brings
the sector into mesh at the high point of the worm.

57. Turn the eccentric adjusting sleeve (F), Figure (1601),
clockwise very gradually, checking at each movement the
amount of lost motion still existing at the ball arm. Adjust to
point where lash can be just felt at end of ball arm, being sure
to finish movement of eccentric adjustment sleeve (F) in
clockwise direction.
58. Turn hand wheel throughout full travel to test for free
operation. If too tight, turn eccentric adjusting sleeve (F) coun-
terclockwise to free and readjust more carefully.
59. Tighten eccentric adjusting sleeve jam nut (E) securely
first and follow likewise with housing cover nuts (A). Very
important.
NOTE: The worm is generated in such manner that close
mesh with sector teeth is provided at the mid- position or place
corresponding to the straight ahead driving range with gradual
relief toward the extremes. Since any normal wear is most
pronounced at mid-position, this provision allows for subse-
quent adjustment without fear of binding toward the extremes.
When the sector teeth are properly centralized in relation
to the worm thread, there should be an equal amount of lash in
the mesh of these parts at A turn of hand wheel each side of
mid-position previously described. If this is not the case,
correct
